OBJECTIVE:
Small ubiquitin-related modifiers (SUMOs) are a group of post-translational modification proteins extensively expressed in eukaryotes. Abnormal SUMOylation can lead to the development of various diseases. This article summarizes the progress on research of the role of SUMOs in various types of kidney diseases to further increase the understanding of the regulatory functions of SUMOylation in the pathogenesis of kidney diseases.
DATA SOURCES:
This review was based on articles published in the PubMed databases up to January 2018, using the keywords including "SUMOs," "SUMOylation," and "kidney diseases."
STUDY SELECTION:
Original articles and critical reviews about SUMOs and kidney disease were selected for this review. A total of 50 studies were in English.
RESULTS:
SUMO participates in the activation of NF-κB inflammatory signaling pathway, playing a central regulatory role in the inflammation and progression of DN, and the secretion of various chemokines in AKI. SUMO involves in the regulation of TG2 and Nrf2 antioxidant stress, affecting renal tubular injury in AKI. SUMO affects the MAPK/ERK pathway, regulating intracellular signal transduction, modulating the transcription and expression of effector molecules in DN. SUMO contributes to the TGF-β/Smad pathway, leading to fibrosis of the kidney. The conjugate combination of SUMO and p53 regulates cell proliferation and apoptosis, and participates in the regulation of tumorigenesis. In addition, SUMOylation of MITF modulates renal tumors secondary to melanoma, Similarly, SUMOylation of tumor suppressor gene VHL regulates the occurrence of renal cell carcinoma in VHL syndrome.
CONCLUSIONS
Tissue injury, inflammatory responses, fibrosis, apoptosis, and tumor proliferation in kidney diseases all involve SUMOs. Further research of the substrate SUMOylation and regulatory mechanisms of SUMO in kidney diseases will improve and develop new treatment measures and strategies targeting kidney diseases.

The development of a perirenal hematoma is rare and primarily the result of trauma, malignancy, or a connective tissue disease. Infrequently, a continuous or even mild trauma can cause a perirenal hematoma. Here, we report a case involving the development of a perirenal hematoma after excessive hula-hooping in the absence of a major trauma history.

5.Hazardous environmental factors causing renal damage in children.
Chinese Journal of Contemporary Pediatrics 2014;16(4):319-324
Hazardous environmental factors invade the body through multiple routes, including ingestion, inhalation and absorption by contact with the skin and mucous membrane. They are from various sources and soil, water, air, building and decorative materials, foods and daily necessities are the main carriers. According to their physical and chemical properties and morphological characteristics, these hazardous factors are classified as metals, inorganic matter, organic matter, radioactive substances, biological toxins, viruses, bacteria, mycoplasmas, chlamydiae and parasites. They cause diseases through blood and urine and also have kidney susceptibility. This article suggests that pediatricians should fully understand the characteristics and seriousness of hazardous environmental factors that cause renal damage, and pay attention to the prevention and control of these factors so as to minimize renal damage in children.

To investigate the effects of mycophenolate mofetil (MMF) on the process of renal interstitial fibrosis, unilateral ureteral obstruction (UUO) model was established in rats. Twenty Sprague-Dawley rats underwent UUO and received vehicle (n = 10) or MMF (20 mg.kg-1.d-1, by daily gastric gavage, n = 10) during a period of 5 days following surgery, and the additional 10 rats were served as sham-operated group. The rats were killed 5 days after surgery. Immunohistochemistry was performed on renal tissue for proliferating cell nuclear antigen (PCNA), alpha-smooth muscle actin (alpha-SMA) and type I and III collagen (col I, col III). Histological studies were also done by MASSON staining. Five days after surgery, proliferating cells in tubules, interstitium as well as interstitial myofibroblast (MyoF) infiltration and interstitial col I, col III deposition were all significantly reduced by MMF treatment. MMF also alleviated the histological changes of UUO rats. These results suggested that the reduction of interstitial MyoF infiltration may be an important event by which MMF prevents renal injury caused by UUO and MMF could be used to limit the progression of renal fibrosis.

Nocardia is a significant opportunistic pathogen in patients with compromised immunity. The authors isolated N. asteroides from an abscess of the axilla and from respiratory specimens of a renal allograft patient with pneumonia. Direct smear of the sputum and bronchial washing specimens showed many branching, filamentous forms which were gram-positive and acid fast. Culture yielded slow growing small white colonies which became orange on further incubation. Aerial hyphae were produced. Identification of the species was based on typical cultural and biochemical tests. The isolate was susceptible to amikacin, minocycline and rifamipicin. The patient became afebrile after 8 weeks of treatment with cotrimoxazole and brief treatment with other antimicrobial agents.
